   Abstract : Magnetic materials are indispensable in modern day society. The vast majority of energy generation and conversion involves some kind of magnetic material, and several other applications such as data storage also use them. READ MORE

4. 2. Multifunctional magnetic materials prepared by Pulsed Laser Deposition

   Author : Sandeep Nagar; Lyuba Belova; K. Venkat Rao; Prashanth Kamath; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic materials; thin films; pulsed laser depsoition; spintronics; chromites; MgO; NEMS; MEMS;

   Abstract :      Pulsed LASER deposition (PLD) is widely recognized as excellent deposition technique owing to stoichiometric transfer of target material, easy preparation and high quality. Thin films from few nanometers to micrometer regime can be fabricated with equal ease. READ MORE

5. 3. Ferromagnetic resonance in films with growth induced anisotropy
