title = "119Sn M{\"o}ssbauer studies in antiferromagnetic La2CuO4",
abstract = "M{\"o}ssbauer Spectroscopy (MS) studies of 119Sn were carried out in antiferromagnetic La2(Cu.99Sn.01)O4. The 1 at% 119Sn4+ impurity in the form of SnO2 was first diffused in CuO, and its substitution for Cu2+ was confirmed. Spectra recorded at T> 120 K show a single site quadrupole splitting. At T < 120 K, a magnetic interaction is observed, reaching a saturation with hyperfine field, Heff = 8.7 KOe at T ≤ 30 K. From the combined quadrupole-magnetic interaction at T ≤ TN, both the η-parameter and the angle θ{symbol} formed by qzz and Heff were determined. The significance of the transferred hyperfine interaction in terms of spin-structure is outlined. The feasibility of applying 119Sn MS as a microscopic probe in the Cu-O layers and its comparison with corresponding 57Fe MS is discussed.",

note = "Funding Information: T = 77 K was found to be 395 KOe. Clearly the value of this ~n+yperfine field originates from the Fe moment itself; its value and its temperature dependence may or may not reflect magnetic interactions originating from the Cu moments. In this respect the advantage of the 119Sn MS as {"}neutral{"} diamagnetic probe is evident.
