1. 1. Magnetization dynamics in bistable systems

   University essay from Uppsala universitet/Materialfysik

   Author : Sven Backlund; [2023]
   Keywords : magnetism; magneto-optics; magnetization dynamics;

   Abstract : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. READ MORE

3. 2. Tailoring the magnetic anisotropy in amorphous FeZr-based thin films on flexible and solid substrates

   University essay from

   Author : Matteo Menniti; [2018]
   Keywords : amorphous; magnetic; materials; anisotropy; material characterization; iron; cobalt; zirconium; boron; moke; magneto optical; tailoring; material design; flexible; magnetostriction; functional materials; sensor;

   Abstract : In this thesis the magnetic properties of novel amorphous magnetic materials grown on a flexible substrate of polyethylene naphthalate and a silicon wafer have been analyzed and characterized. The analyzed films are two films of amorphous Cobalt-Iron-Zirconium(Co36Fe53Zr11 & Co37Fe55Zr8) grown on the flexible substrate and two films of amorphous (Fe89Zr11) doped with boron (B). READ MORE

4. 3. Magnetocrystalline Anisotropy in(FexNi1-x)2B Materials

   University essay from Uppsala universitet/Materialteori

   Author : Anders Stangel; [2016]
   Keywords : Magnetocrystalline anisotropy; magnetism; DFT; permanent magnets;

   Abstract : The magnetic properties of the (FexNi1-x)2B family of materials are explored using DFT calculations utilizing the FPLO and SPR-KKR code packages. It is found that a uniaxial magnetocrystalline anisotropy exists at around x = 0.8 with a magnetocrystalline anisotropy energy at around 0.3 MJ/m^3. READ MORE

5. 4. Growth and characterization of advanced layered thin film structures : Amorphous SmCo thin film alloys

   University essay from Institutionen för fysik och astronomi

   Author : Andreas Roos; [2012]
   Keywords : uniaxial magnetic anisotropy; samarium Cobalt alloy; amorphous thin film; DC magnetron sputtering; magneto optic Kerr effect; x-ray scattering;

   Abstract : This report describes the growth and characterization of thin amorphous samarium-cobalt alloy films. The samarium-cobalt alloy was grown by DC magnetron sputtering in the presence of an external magnetic field parallel to the thin film. The external magnetic field induces a uniaxial in-plane magnetic anisotropy in the samarium-cobalt alloy. READ MORE
