Intermediate phase in the spiral antiferromagnet Ba_2CuGe_2O_7
J. Chovan, N. Papanicolaou, S. Komineas
The magnetic compound Ba_2CuGe_2O_7 has recently been shown to be an essentially two-dimensional spiral antiferromagnet that exhibits an incommensurate-to-commensurate phase transi…

Low-frequency spin dynamics in the orthorombic phase of La_2CuO_4
J. Chovan, N. Papanicolaou
An effective field theory is derived that describes the low-frequency spin dynamics in the low-temperature orthorombic phase of La_2CuO_4. Restricted to a single CuO_2 layer the ef…
