Abstract:

The low-temperature specific heat C (p) of La(Fe0.873Co0.007Al0.12)(13) compound has been measured in two states: (i) antiferromagnetic (AFM) with a Neel temperature of T-N = 192 K and (ii) ferromagnetic (FM). The FM order appears at T = 4.2 K in a sample exposed to an external magnetic field with induction B (C) >= 2.5 T and is retained for a long time in a zero field at temperatures up to T{*}(C) = 23 K. The coefficient gamma(FM) in the low-temperature specific heat C = gamma T + beta T-3 in the FM state differs quite insignificantly from that (gamma(AFM)) in the AFM state. Contributions to the low-temperature specific heat, which are related to a change in the elastic and magnetoelastic energy caused by magnetostrictive deformations, are considered.
