A rare ferromagnet-antiferromagnet transition is known to exist in the solid-solution Y_1\ensuremath-xLaxTiO3 at x \ensuremath≈ 0.3. Here, the authors study this transition using a unique battery of techniques, including magnetometry, x-ray absorption spectroscopy, x-ray magnetic circular dichroism, muon spin rotation, neutron diffraction, and small-angle neutron scattering. The thermal magnetic phase transitions are observed not to be of conventional second-order type, but rather to be first order in nature. Furthermore, complex changes in the magnetic ground state are revealed.
