Magnetics Society Distinguished Lecturers for 2005
Half-Metals, Spin Torque, and Nanorings
Chia-Ling Chien
The Johns Hopkins University
The exploration of magnetic nanostructures in recent years has resulted in a string of discoveries such as interlayer coupling, giant magnetoresistance (GMR), exchange bias, and tunneling magnetoresistance. Some of these effects were utilized as read-heads in high-density magnetic recording and non-volatile magnetic storage only a few years after the original discovery. In this talk, I will describe several new topics in magnetic nanostructures from inception to realization to potential applications. |

Micro Fabrication Techniques for Magnetic Information Storage Devices:
From Bubbles to Thin Film Recording Heads to Nano Magnetic Structures
Robert E. Fontana, Jr.
Hitachi Global Storage Technologies
This lecture examines magnetic device structures from the perspective of thin film processing. Techniques for forming magnetic device structure minimum features will be compared with semiconductor processing. Future storage density growth in both magnetic memories and magnetic recording will be projected using semiconductor roadmaps. The “nano” characteristics (thickness and length scale) of next generation magnetic thin film heads and magnetic memory devices will be compared with solid state semiconductor designs. |

Dynamics in magnetic micro- and nanostructures
Burkard Hillebrands
Technische Universität Kaiserslautern
For applications in sensors and in data storage, the dynamic properties of micro- and nanostructures gain increasing attendance. The fundamental excitations in these objects are con-fined spin waves, and it is useful in particular to understand their properties in view of the noise spectrum in sensor and MRAM applications. |
