Results of a neutron diffraction study of the field-induced magnetic form factor of pure antiferromagnetic chromium are presented. The data is analysed by means of a classical Fourier technique as well as a maximum entropy analysis. In agreement with

A graphite double monochromator for X-ray synchrotron radiation is presented for specific applications. The main feature is a broad wavelength band and a high collimation of the reflected beam. The relaxed resolution in energy results in an intensity

In the pyrochlore lattice, the magnetic ions sit at the corners of a framework of corner-sharing tetrahedra. It is well known that this lattice results in a very high degree of geometrical frustration for antiferromagnetic interactions, but it will b

In the pyrochlore antiferromagnets, the magnetic ions are situated at the vertices of a framework of corner-sharing tetrahedra. The result is intense geometrical frustration of the magnetic interactions. We present the results of a single-crystal neu
