Evidence of Spin Canting, Metamagnetism, Negative Coercivity and Slow Relaxation in a Two‐Dimensional Network of {Mn6} Cages. Issue 3 (8th September 2017) - Dendrinou‐Samara, Catherine
Abstract : The synthesis, crystal structure and magnetic studies are reported for a two‐dimensional network of mixed‐valent {Mn6 } cages. The compound contains three different bridging ligands: pivalate, phenylphosphonate and partially deprotonated triethanolamine. The result of using three bridging ligands is a complex structure involving a {Mn III 2 Mn II 4 } edge‐sharing bitetrahedron that interlinks, forming a layered structure. Weak intercage interactions lead to a remarkably complicated magnetic behaviour, with a phase transition at 2.1 K leading to a canted antiferromagnetic state. Abstract : A 2D network of covalently linked {Mn2 III Mn4 II } entities with two different orientations of their Jahn–Teller axes and complex magnetic behaviour, displaying simultaneously weak ferromagnetism, spin canting, slow magnetic relaxation, metamagnetic behaviour and an unusual reversed hysteresis.
