Query: Avalanche-like metamagnetic transition in (LaNd)CaMnO manganites   We investigate the behavior of ultrasharp metamagnetic transitions in
La(5/8-y)Nd(y)Ca(3/8)MnO(3) manganites. These compounds change from a low
temperature ferromagnetic metallic state at low Nd doping to a charge-ordered
antiferromagnetic insulator for high Nd content. At an intermediate doping a
phase-separated state is established. At low temperatures (2 K), we observe an
avalanche-like field-induced metamagnetic transition, when the entire compound
changes abruptly from one phase to the other. We investigate the signatures of
this ultrasharp transition using magnetization and specific heat measurements.
We observe a first order transition in the specific heat associated with
discontinuous jumps in the magnetization. A strong increase of the sample
temperature is simultaneously observed. The results are interpret in terms of
latent heat release from the field induced enhancement of the ferromagnetic
fraction, triggering the avalanche process.
