Ta. Ivanova et al., Characteristics of the structural properties and the electric conductivityin LaSrAl1-xNixO4 ceramics caused by the Jahn-Teller effect, PHYS SOL ST, 41(3), 1999, pp. 375-378
In studying LaSrAl1-xNixO4 ceramics, anomalies are detected in the concentr
ation dependences of the lattice parameter c, the electrical resistance, an
d the sign change of the Hall constant at x approximate to 0.6. It is shown
that the collection of observed phenomena can be interpreted as a manifest
ation of the Jahn-Teller nature of low-spin Ni3+ centers. (C) 1999 American
