摘要：

We extend our previous theoretical study of Mn-based orthorhombic metamagnets to those that possess large nearest neighbor Mn-Mn separations (d(1) greater than or similar to 3.22 angstrom). Based on our calculations, we design and synthesize a series of alloys, CoMnGe1-xPx, to experimentally demonstrate the validity of the model. Unusually, we predict and prepare several metamagnets from two ferromagnetic end-members, thus demonstrating a new example of how to vary crystal structure, within the Pnma symmetry group, to provide highly tunable metamagnetism.
