I need some help with LT Spice

I am doing some work with SQUIDs and I need to simulate the hysteresis of these circuits.

What I need is a command to do a DC sweep from zero up to 4fV and back down to 0V.

The problem is that the .dc command in spice only accepts a start, stop and increment value.

I then want to plot an output voltage against this input.

I have tried to do a .tran analysis but this doesn't give the desired results, because

the plot is then done vs. time and thats not what I want...

If there is anyone that can please help me, I can include the netlist as well.
