The paper proposes a new device design for enhancing the mass sensitivity of SAW delay line oscillator sensors. Considering implicit dependence of the phase condition of oscillation on SAW velocity and delay path length it is theoretically shown that a chirped delay line can either reduce or enhance the mass sensitivity depending upon the characteristics of the chirp function. It is found that a linear FM up-chirp always reduces the mass sensitivity. The linear Barbour Bedale Pas Cher FM down-chirp devices with commonly Barbour Belgique implemented chirp parameters for matched filtering applications also reduce the mass sensitivity, though they offer the possibility of enhanced sensitivity through Barbour Manteau Homme steep chirp slope implementation. A nonlinear chirp consisted of sum of linear and sinusoidal terms is proposed for practical implementation of SAW dispersive delay lines that can dramatically enhance the mass sensitivity of SAW chemical sensors.

A novel scheme is proposed to investigate the possible giant Kerr nonlinearity in a crystal of molecular magnets. The crystal is subjected to one dc   magnetic field and two probe and coupling acac magnetic fields. By studying the steady-state behavior of the medium, we show that an enhanced Kerr nonlinearity with negligible absorption can be achieved under condition of slow light levels, just by properly adjusting the coupling field. Also, the transient evolution of nonlinear dispersion is proposed. It is found that the frequency detunings of probe and coupling fields, as well as the intensity of coupling field, lead to the large Kerr nonlinearity. Our results can be used as a guideline for optimizing and controlling the switching process in the crystal of molecular magnets, which is much more practical than that in the atomic system because of its flexible design and the long relaxation times.
