Ferrimagnetic and spin glass behaviour in SrMn2+3Ti4+14M3+4O38 (M = Ti and Fe) synthetic crichtonites†
Abstract
Novel SrMn3Ti14M4O38 (M = Ti and Fe) compounds with a crichtonite-type structure are reported herein. M = Ti shows a ferrimagnetic behavior at TN = 15 K, while M = Fe creates a ferromagnetic cluster-glass at Tf = 8 K via positional disorder. This family offers a promising magnetic playground.
