| Outline and Purpose of the Course | Phase Transitions: Aiming at understanding the diversity and universality of phase transitions, physical properties of those materials that undergo phase transitions are investigated experimentally, among which are ferromagnetic-paramagnetic transitions in magnetic materials, order-disorder transitions in alloys and liquid crystals. Microscopic mechanisms that induce phase transitions are also elucidated through observation and analysis of anomalous behaviors near the transition points. | |||
| Course Goals | The purposes are acquirement of basic knowledge of Condensed Matter Physics, understanding the principles of experimental methods and development of ability to extract physical pictures from experimental results. | |||
| Schedule and Contents |
☆The first half of the course [i.e 1st to 7th weeks] At the 1st week, overview of the B1 activity is given. From the 2nd week, seminars on both Condensed Matter Physics (A) and related experimental techniques (B) are held. The former (A) is as follows: Crystal structure, reciprocal lattice, lattice vibration, lattice specific heat [2nd & 3rd weeks], Free electron gas, magnetism (dia-, para-, ferro-magnetisms, magnetic domain) [4th and 5th weeks], Ordered alloys [6th week] and Critical phenomena [7th week]. Thereby“Introduction to Solid State Physics”, by C. Kittel, is used as a textbook from the 2nd to 5th week, and thereafter printed materials provided by the teaching staffs are used. For the latter (B), one technique is learned at each seminar: electronics [2nd week], vacuum technique [3rd week], temperature control [4th week], generating magnetic field [5th week], laser spectroscopy [6th week]. Details about individual experiments are discussed thereafter. ☆☆The second half of the course [i.e. 8th to 14th weeks] Experiments are carried out on one of the following themes. ・Ferro- to para-magnetic phase transitions and order-disorder phase transitions, detected by electrical resistivity measurements. ・Ferro- to para-magnetic phase transitions, detected by magnetic susceptibility measurements. ・Phase transition from liquid crystal to isotropic liquid and the Fredericks transition, detected by ellipsometric measurements. Note that, while the seminars are held at the 3rd and 4th periods on Mondays, the experiments can be done every day. ◎The experimental results are orally presented at the last week, followed by a terminal report. |

| Course Requirements | None | |||
| Study outside of Class (preparation and review) |
A reporter at the seminar is obliged to prepare a resume. Prior to the experiment, image-training of its procedure is highly desired, and posterior to it, its performance should be critically reviewed. In case of unsuccessful experiment a possible way of improvement must be devised. |
