Evolution from Ferromagnetism to Antiferromagnetism in the CeTi_1-xV_xGe₃ System

The suppression of ferromagnetism in metallic systems may result in the appearance of modulated magnetic phases. Recent studies have shown that the application of pressure in the CeTiGe₃ system is a possible example of such phenomenon. By combining magnetic field and pressure, a wing-structure phase diagram with a quantum tricritical point is observed [1]. Here we show that substituting vanadium in place of titanium will suppress ferromagnetism, and an antiferromagnetic state is observed near the V-rich end. We discuss the evolution of the ordering temperature and of the magnetic anisotropy as Ti is progressively substituted by V in single crystals of the CeTi_1-xV_xGe₃ series.
