Single-crystals of the novel mixed valent cobaltite YBaCo 4 O 7+Ξ΄ have been synthesized. Careful magnetization measurements gave evidence of a ferrimagnetic phase with a T C β 50 K and a large coercive field of βΌ1 T at 5 K. As no substitution of a divalent cation for yttrium was realized, it is poss
