Abstract: The invention concerns a device for heating an object (6) in an intense magnetic field, comprising:—a light source (1), an optic fiber (2) for transporting the light emitted by said light source (1) and emitting a beam of light in the direction of the object (6) to be heated, a converging optical system (3), a diaphragm (4) positioned at the focusing point of the optical system (3),—a reflector (5), whereof the inner wall is defined by the revolution of a semi-parabola around an axis perpendicular to the optical axis of the parabola and passing through the focal point of said parabola, the optical axis of said reflector (5) coinciding with the optical axis (A) of the optical system (3) and the focal point (F?) of said reflector coinciding with the focusing point of said optical system (3).

Abstract: The disclosure concerns a method for treating a material in a static magnetic field having an intensity of more than 1 Tesla, including the following steps: a first step to heat the material, a second step to apply to the material a thermal shock and/or thermomechanical treatment and/or chemical treatment, wherein during at least the second treatment step, the material is subjected to the magnetic field while being held in position within the magnetic field. The disclosure also concerns a device for implementing the method, the device including: a support to hold the material during the steps of the cycle, a device to apply the static magnetic field capable of generating a magnetic field of intensity higher than 1 Tesla, a first system allowing heating of the material, a second system for implementing the subsequent step of the cycle.
