Observation of magnetic ordering for layered (2-D) potassium diruthenium tetracarbonate, K3[Ru(II/III)2(O2CO)4]: a rare second row transition metal-based magnet.
The detailed magnetic behavior of K(3)[Ru(2)(CO(3))(4)].xH(2)O (x = 2) reveals that it has a 2-K magnetization at 5 T of 11 125 emu Oe/mol, a 50-Oe coercive field, and a remnant magnetization of 670 emu Oe/mol. It magnetically orders as a canted ferrimagnet below 4.2 K, and is a rare example of a magnetically ordered material based on a second row transition metal. The magnetic ordering confirms that the S not equal to 0 M(II) site that bridges the layers in previously reported H(x)K(1-x)M(II)-[Ru(II/III)(2)(CO(3))(4)](H(2)O)(y)(MeOH)(z) (M = Mn, Fe, Co, Ni, Cu, Mg) does not contribute to the magnetic behavior that leads to magnetic ordering.
