Notes:
Ferromagnetic shape memory alloy of nominal composition Ni50Mn35Sn15 has beeninvestigated by magnetic and transport measurements. Clear signature of first order martensitictransition is observed over a region around 180 K in resistivity, dc magnetization and acsusceptibility data. Field-cooled and zero-field-cooled magnetizations diverge below the martensitictransition, signifying magneto-thermal irreversibility originating from pinning by variants. Thesample shows large negative magneto-resistance (-25% at 90 kOe) in the region of martensitictransition, which was found to be highly irreversible. A clear correspondence between magnetoresistanceand dc magnetization is observed above the field of technical saturation
