1. A particulate material comprising: a shaped abrasive particle having a body comprising:a first layer;a second layer overlying the first layer and comprising a second dopant; andwherein the first layer and the second layer are arranged in a stepped configuration with respect to each other, and wherein the stepped configuration is defined by a lateral shift of the first layer with respect to the second layer. 2. The particulate material of claim 1, wherein the lateral shift comprises a lateral distance of at least about 1% of the total length of the body. 3. The particulate material of claim 1, wherein the first layer comprises a first thickness and the second layer comprises a second thickness, and wherein the first thickness and the second thickness are different by at least about 5%. 4. The particulate material of claim 1, wherein the first layer comprises a first thickness of at least about 5% of an average thickness of the body, and wherein the second layer comprises a second thickness of at least about 5% of an average thickness of the body. 5. The particulate material of claim 1, wherein the second dopant is selected from the group consisting of alkali elements, alkaline earth elements, rare-earth elements, hafnium (Hf), zirconium (Zr), niobium (Nb), tantalum (Ta), molybdenum (Mo), and a combination thereof. 6. The particulate material of claim 1, wherein the second dopant comprises zirconium. 7. The particulate material of claim 1, wherein the second dopant comprises zirconia, and wherein the second layer comprises a greater content of zirconia than a content of zirconia in the first layer. 8. The particulate material of claim 1, wherein the first layer defines a first two-dimensional shape as viewed in a plane defined by a length and a width of the body selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 9. The particulate material of claim 8, wherein the second layer defines a second two-dimensional shape as viewed in a plane defined by a length and a width of the body selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 10. The particulate material of claim 9, wherein the second two-dimensional shape is different than the first two-dimensional shape. 11. A particulate material comprising: a shaped abrasive particle having a body comprising:a first layer;a second layer overlying the first layer and comprising a second dopant, wherein the second dopant comprises zirconia, and wherein the second layer comprises a greater content of zirconia than a content of zirconia in the first layer; andwherein the first layer and the second layer are arranged in a stepped configuration with respect to each other. 12. The particulate material of claim 11, wherein the stepped configuration is defined by a lateral shift of the first layer with respect to the second layer. 13. The particulate material of claim 12, wherein the lateral shift comprises a lateral distance of at least about 1% of the total length of the body. 14. The particulate material of claim 11, wherein the first layer comprises a first thickness and the second layer comprises a second thickness, and wherein the first thickness and the second thickness are different by at least about 5%. 15. The particulate material of claim 11, wherein the first layer comprises a first thickness of at least about 5% of an average thickness of the body, and wherein the second layer comprises a second thickness of at least about 5% of an average thickness of the body. 16. The particulate material of claim 11, wherein the first layer defines a first two-dimensional shape as viewed in a plane defined by a length and a width of the body selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 17. The particulate material of claim 16, wherein the second layer defines a second two-dimensional shape as viewed in a plane defined by a length and a width of the body selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 18. The particulate material of claim 17, wherein the second two-dimensional shape is different than the first two-dimensional shape. 19. The particulate material of claim 1, wherein the body comprises an oxide. 20. The particulate material of claim 11, wherein the body comprises an oxide.
