Abstract
The ferromagnetic (FM)–paramagnetic (PM) first-order transition is induced by pressure around room temperature for La(Fe0.88Si0.12)13H1.25 with the Curie temperature TC = 293 K. The spontaneous magnetization at room temperature is significantly decreased due to the phase transition induced by pressure. In addition, the low-field magnetic susceptibility exhibits a response against hydrostatic pressures. From these results, the pressure detection using FM–PM transition has been demonstrated. By dispersing the coarse-grained La(Fe0.88Si0.12)13H1.25 into a column-shaped epoxy resin, the susceptibility change against the unidirectional stress is detected by the inductance of a coil. The inductance response is scarcely changed after 400 cycles of loading. Relating to endurance, the thermal phase stability of hydrides annealed at various temperatures has been investigated. The hydrogen desorption rate obtained from the Arrhenius plots is negligibly small around room temperature, proving that La(Fe0.88Si0.12)13H1.25 has high thermal phase stability over a long period of time.
