← ScienceWhich magnetic consequence results when hydrostatic pressure alters a crystal lattice?
A)Increased Curie temperature
B)Decreased Neel temperature
C)Change in magnetic anisotropy✓
D)Suppressed spin wave excitation
💡 Explanation
When pressure changes the atomic spacing of the crystal lattice, magnetocrystalline anisotropy is altered because it modifies the electron band structure, therefore changing the preferred direction of magnetization, rather than affecting temperature scales or spin wave dynamics.
