Abstract: | The pseudobinary CrAsTiAs system has been investigated by X-ray and neutron diffraction and magnetic susceptibility measurements at temperatures between 10 and 1000 K. The phase diagram includes paramagnetic regions with the MnP-, NiAs-, and TiP-type structures and a low-temperature helimagnetic, MnP-type state for0.00 ≦ t ≦ 0.10 of Cr1?tTitAs. The first-order para- to helimagnetic transition in Cr1?tTitAs is accompanied by a hysteresis of 10–15 K. The results are discussed in relation to the findings for other Cr1?tTtAs(T =V, Mn, Fe, Co, Ni) andCrAs1?xXx (X = P, Sb, Se) phases. |
