CAUTION No one with a pacemaker should approach within 30 cm of an NMR instrument. Higher specification instruments require further caution. If in doubt, consult a doctor and the equipment manufacturer. Keep magnetic storage devices (including credit cards) away from the measurement coil. 

C-N thin films could be an attractive diamond-like coating material for thermal management in multi-chip modules and micro-scale devices [35]. The field-emission properties of C-N thin films were studied, and indicated an enhancement in the emitted current density [36]. It has been predicted that this material would, as a consequence, have a wide range of potential applications, such as in electronic packaging and wear protective coatings for magnetic storage devices [37]. 

One area where the relationship between the structure of the polymer matrix and the physical processes of the thin layer has been studied in detail is that of electrodes modified with polymer films. The polymer materials investigated in these studies include both conducting and redox polymers. Such investigations have been driven by the many potential applications for these materials. Conducting polymers have been applied in sensors, electrolytic capacitors, batteries, magnetic storage devices, electrostatic loudspeakers and artificial muscles. On the other hand, the development of electrodes coated with redox polymers have been used extensively to develop electrochemical sensors and biosensors. In this discussion,... 

Small Pt clusters have been studied in detail by several groups using a variety of methods because of their importance in catalysis. Cobalt clusters, on the other hand, have been investigated because of their importance in magnetic storage devices. " Understanding the electronic stracture of small bimetallic Co-Pt clusters and their interaction with molecules and substrates, however, is still a challenging work. 

Another recent discovery is that of collosal magnetoresistance (CMR), in which the electrical resistance of a material changes dramatically in the presence of a magnetic field. This property is important in the devices which read data on magnetic storage devices, such as computer hard discs. 

Section IV deals with the application of electrochemical technologies to magnetic-storage devices. In the field of magnetic information storage, hard discs, floppy discs, and tape drives are widely used. Electrochemical deposition techniques are essential in their production and this is the raison d etat for its inclusion in this chapter. 

Storage devices, such as lithium batteries, fuel cells and supercapacitors magnetic storage devices, i.e., soft and alloy films bio-chips for sensing genetic changes and water toxicity and MEMS/NEMS devices for a variety of important applications.
