"Magnetic and transport properties of the layered transition-metal pnictides R3T4As4O2−δ (R = La, Ce, Pr, Nd, and Sm, T = Ni, Cu)." <i>Physical Review B,</i> 89, (2014) American Physical Society: 94405. http://dx.doi.org/10.1103/PhysRevB.89.094405.https://hdl.handle.net/1911/75574The magnetic and transport properties of the novel R3T 4As4O2−δ (R = La, Ce, Pr, Nd and Sm, T = Ni and Cu) layered materials were studied using structural and physical properties measurements. Varying the rare-earth ion led to the observation of diverse physical properties including superconductivity for R = La and T = Ni, ferromagnetic or antiferromagnetic order for R = Ce, Pr, and Sm, or spin-glass behavior in Nd3Ni4As4O2−δ. These complex magnetic and electronic properties are discussed in light of the crystalline anisotropy in these layered compounds.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
