The magnetic phase diagram is found to be composed of five regions: four of wich are collinear spin arrangement and one is of double helical spin arrangement. The values of exchange integrals of Bi₂CuO₄ estimated by Aïn et al from their own neutron scattering data are in the region where the observed collinear spin arrangement is stabilized., Article, 信州大学理学部紀要 30(2): 55-67(1996)}, pages = {55--67}, title = {Magnetic Phase Diagram of Bi₂CuO₄}, volume = {30}, year = {1996} }
