We have considered the structure and energetics of planar and linear soliton states in Ferronematics in a magnetic field. The 2π planar soliton in a ferronematic with positive diamagnetic anisotropy becomes unstable above a threshold field, splitting into two π planar solitons. When diamagnetic anisotropy is negative, we get the classical linear soliton below a threshold field. This becomes unstable above the threshold field leading to two new types of linear solitons. The structures of these solitons appears to be very sensitive to elastic anisotropy. An extension of this to nematics having solute molecules has also been considered.
