Abstract

We report an unusual sensitivity of electrical resistivity (ρ) to an application of a small magnetic field in an intermetallic compound, Tb5Si3, under pressure. In this compound, there is a magnetic-field-induced first-order magnetic transition at 1.8 K. Under pressure, there is a metastable magnetic phase after reducing the field to zero. This metastable phase is relatively of higher ρ and interestingly a small magnetic field (< 2 kOe) in the reverse direction results in a sharp fall of ρ to restore virgin state ρ. The present finding could be relevant in spintronic applications.
